Development of a technique to recycle glass-fibre reinforced phenolic prepreg waste as reinforcing filler in PP and PA6

A technique to recycle glass-fibre reinforced phenolic prepreg waste as reinforcing filler in PP and PA6 was developed. The large amount of phenolic prepreg waste, generated in the production of grinding wheels, is currently disposed of in landfills. A technique was developed to use the wastes as filler in thermoplastics, thus reducing the overall environmental impact of the phenolic grinding wheel production. The results particularly point out the possibilities to control the interfacial properties, and hence the composite mechanical properties, using various chemical coupling agents and interfacial compatibilisers. In addition, the most important parameters of the production, e.g. size reduction of recyclate and compounding procedures, were identified and optimised.
